<Columns>
<asp:BoundField DataField="EmployeeID" HeaderText="Employee ID" ReadOnly="True" SortExpression="EmployeeID" />
<asp:BoundField DataField="FirstName" HeaderText="Employee Name" ReadOnly="True" SortExpression="FirstName" />

If you don't already have a strong type defined to represent your selected Employee, you could create a Dictionary to store your selected employees. Upon completing your iteration over GridView1's rows to get the selected employees, you could use the dictionary as the datasource for GridView2 and bind to the Key and Value of each entry.

protected void btnAssign_Click(object sender, EventArgs e)
{
    Dictionary<int, string> selectedEmployees = new Dictionary<int, string>();
    foreach (GridViewRow row in GridView1.Rows)
    {
        if (row.RowType == DataControlRowType.DataRow)
        {
           CheckBox chkRow = (row.Cells[2].FindControl("CheckBox1") as CheckBox);
           if (chkRow.Checked)
            {
                selectedEmployees.Add(int.Parse(row.Cells[0].Text), row.Cells[1].Text);
            }
        }
    }

    if (selectedEmployees.Any())
    {
        gridView2.DataSource = selectedEmployees;
        gridView2.DataBind();
    }

}
